[4/7] git commit: Add a new driver, tests and documentation for CloudSigma API v2.0.

Add a new driver, tests and documentation for CloudSigma API v2.0.

Also update existing driver for API v1.0 and other affected code:

- Update existing driver for API version 1.0 and prefix 1.0 classes with "1_0"
- Update existing 1.0 driver to support "region" argument. This way porting
  existing code to API v2.0 will be easier.
- Add new CloudSigmaNodeDriver class which can be instantiated directly. Which
  API version is used is dictated by the "api_version" kwarg which defaults to
  2.0.
- Add new libcloud.common.cloudsigma module which holds common functionality
  for CloudSigma drivers
- Update INSTANCE_TYPES to be a list so output of list_sizes() method is always
  returned in the same order.

+CloudSigma Compute Driver Documentation
+=======================================
+
+`CloudSigma`_ is a pure IaaS provided based in Zurich, Switzerland with
+data centers in Zurich, Switzerland, Las Vegas, United States and Washington DC,
+United States.
+
+CloudSigma driver supports working with legacy `API v1.0`_ and a new and
+actively supported `API v2.0`_. API v1.0 has been deprecated and as such,
+you are strongly encouraged to migrate any existing code which uses API v1.0 to
+API v2.0.
+
+Instantiating a driver
+----------------------
+
+CloudSigma driver constructor takes different arguments with which you tell
+it which region to connect to, which api version to use and so on.
+
+Available arguments:
+
+* ``region`` - Which region to connect to. Defaults to ``zrh``. All the
+  supported values: ``zrh``, ``lvs``, ``wdc``
+* ``api_version`` - Which API version to use. Defaults to ``2.0``. All the
+  supported values: ``1.0`` (deprecated), ``2.0``
+
+Examples
+--------
+
+1. Connect to zrh region using new API v2.0
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. literalinclude:: /examples/compute/cloudsigma/connect_to_api_2_0.py
+   :language: python
+
+2. Connect to zrh region using deprecated API v1.0
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+As noted above, API 1.0 has been deprecated and you are strongly encouraged to
+migrate any code which uses API 1.0 to API 2.0. This example is only included
+here for completeness.
+
+.. literalinclude:: /examples/compute/cloudsigma/connect_to_api_1_0.py
+   :language: python
+
+3. Create a server using a custom node size
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Unlike most of the other cloud providers out there, CloudSigma is not limited
+to pre-defined instance sizes and allows you to specify your own custom size
+when creating a node.
+
+This means you can totally customize server for your work-load and specify
+exactly how much CPU, memory and disk space you want.
+
+To follow Libcloud standard API, CloudSigma driver also exposes some
+pre-defined instance sizes through the
+:meth:`libcloud.compute.drivers.cloudsigma.CloudSigma_2_0_NodeDriver.list_sizes`
+method.
+
+This example shows how to create a node using a custom size.
+
+.. literalinclude:: /examples/compute/cloudsigma/create_server_custom_size.py
+   :language: python
+
+Keep in mind that there are some limits in place:
+
+* CPU - 1 GHz to 80GHz
+* Memory - 1 GB to 128 GB
+* Disk - 1 GB to 8249 GB
+
+You can find exact limits and free capacity for your account's location using
+:meth:`libcloud.compute.drivers.cloudsigma.CloudSigma_2_0_NodeDriver.ex_list_capabilities`
+method.
+
+4. Associate metadata with a server upon creation
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+CloudSigma allows you to associate arbitrary key / value pairs with each
+server. This examples shows how to do that upon server creation.
+
+.. literalinclude:: /examples/compute/cloudsigma/create_server_with_metadata.py
+   :language: python
+
+4. Add a tag to the server
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+CloudSigma allows you to ogranize resources such as servers and drivers by
+tagging them. This example shows how to do that.
+
+.. literalinclude:: /examples/compute/cloudsigma/tag_server.py
+   :language: python
+
+5. Open a VNC tunnel to the server
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+CloudSigma allows you to connect and manage your server using `VNC`_. To
+connect to the server using VNC, you can use clients such as ``vinagre`` or
+``vncviewer`` on Ubuntu and other Linux distributions.
+
+This example shows how to open a VNC connection to your server and retrieve
+a connection URL.
+
+After you have retrieved the URL, you will also need a password which you
+specified (or it was auto-generated if you haven't specified it) when creating a
+server.
+
+If you can't remember the password, you can use
+:meth:`libcloud.compute.drivers.CloudSigma_2_0_NodeDriver.list_nodes` method
+and access ``node.extra['vnc_password']`` attribute.
+
+After you are done using VNC, it's recommended to close a tunnel using
+:meth:`libcloud.compute.drivers.cloudsigma.CloudSigma_2_0_NodeDriver.ex_close_vnc_tunnel`
+method.
+
+.. literalinclude:: /examples/compute/cloudsigma/open_vnc_tunnel.py
+   :language: python
+
+6. Attach firewall policy to the server
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+CloudSigma allows you to restrict access to your servers by using firewall
+policies. This example shows how to attach an existing policy to all your
+servers tagged with ``database-server``.
+
+.. literalinclude:: /examples/compute/cloudsigma/attach_firewall_policy.py
+   :language: python
